Urban rail vehicle traction and braking integrated test system

Abstract

The invention discloses an urban rail vehicle traction and braking integrated test system, which comprises an information acquisition device, and is characterized by further comprising a traction acquisition unit, a braking acquisition unit, an information exchange device and a test module, wherein the information acquisition device is connected with the traction acquisition unit and the braking acquisition unit through cables for transmitting the acquired signals to the traction acquisition unit and the braking acquisition unit; the traction acquisition unit and the braking acquisition unit provide power for the information acquisition device; the traction acquisition unit and the braking acquisition unit use optical fiber communication to be connected with the information exchange device, and the signals transmitted by the information acquisition device are modulated and then transmitted to the information exchange device; the information exchange device is directly integrated on thetest module through a PXI bus and transmits the information to the test module; and the test module stores, processes and analyzes the information data transmitted by the information exchange device.The system is small in size and simple in operation, and has different functions of testing the traction system and the braking system.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a test system for traction and braking integration of urban railway vehicles. Background technique [0002] The traction and braking system tests of urban railway vehicles include many test items, and the test process involves various physical quantities such as current, voltage, temperature, and pressure, as well as multiple digital signals. In order to detect different sources and different types of signals in traction and braking system tests, testers often use a variety of scattered experimental instruments and equipment, which are large in size and weight, are not easy to carry and cause messy interior. At the same time, the number of test personnel is increased, and the efficiency and reliability of the test are reduced. In addition, a large amount of test data obtained needs to be analyzed and processed by test personnel, and the existing traction and braking system tes...

Problems solved by technology

In order to detect different sources and different types of signals in traction and braking system tests, testers often use a variety of scattered experimental instruments and equipment, which are large in size and weight, are not easy to carry and cause messy interior

At the same time, the number of test personnel is increased, and the efficiency and reliability of the test are reduced

In addition, a large amount of test data obtained needs to be analyzed and processed by test personnel. The existing traction and braking system test technology can no longer meet the needs of the development of my country's rail transit industry.
